I'm going into my Junior year of undergrad as a physics major and can't help but feeling very inadequate. Notwithstanding that I do well in my physics classes, for some reason I don't think I know much physics at all. Surely, I can run through the motions of plugging and chugging equations but I haven't much of a grasp of what I'm studying or what it means. Especially now that my classes are focusing on and pushing deeper into some of the more esoteric topics like QM. Anyone else around this stage tend to have a similar experience?
